| Abstract Scope |
There is significant interest in applying additive manufacturing (AM) techniques to manufacture nuclear fuel systems. Compared to traditional fuel production techniques, AM technique greatly simplifies the fabrication procedure, reduces the production time and cost, and provides additional flexibility to nuclear fuel design for better thermal and mechanical performance. Modeling and simulation can provide the insight for a rational design by addressing the basic science and engineering needs for AM process, leading to a mechanistic understanding of processing-structure-property relationships, which are fundamental to design and develop innovative fabrication techniques for nuclear fuels. At mesoscale, a high-fidelity numerical model including heat transfer, fluid flow and mass transport, is developed in Multiphysics Object Oriented Simulation Environment (MOOSE) to simulate the melt pool physics. The temperature, chemical composition and solidification rate of melt pool can be predicted and thereafter used in lower-length scale model to simulate microstructure evolution. |
